720 Degree Panoramic View Tripod Bracket
This is probably the priciest piece of gear you can get. And it only makes sense to buy one if you have 4 YI cameras. Yeah, obviously this is not for average bloke. But for people seriously involved in aerial photography and even 720 degrees videos, this is quite an interesting tool.
Personally I have not used or tested this one, since its bloody expensive. But I wanted to put it on a list, just because it looks bad-ass.
If you have tested this, by any chance, please let me know in the comments, would love to hear your experience with this out of space tripod.
